The Caribbean LIP eventually separated from the Pacific plate and wandered eastward to its current position between 100-70 million years ago.

[5] Sediment grouped in Megasequence 1 was deposited in the Paleogene and was primarily sourced from South America and the Aves Ridge Sediment grouped in Megasequence 2 was deposited in the early to mid-Miocene and was also sourced from South America.

The Grenada Basin is located in the southeast corner of the Caribbean Plate and is bordered by the Aves Ridge, an extinct volcanic island arc, and the Lesser Antilles, an active volcanic island arc.
